Next year, Formula 1 will see one of its biggest changes in a generation.
Sweeping new regulations will change how cars look, sound and run. The goal is to make them more 鈥渁gile, competitive, safer and more sustainable,” governing body FIA says. Some teams all but abandoned their 2025 car designs early this year in search of the biggest boost they could get in 2026.
The Associated Press spoke with Nikolas Tombazis, who is overseeing the transition to the new rules as the director for single-seater racing series at the FIA, to explain how the changes will affect the action on track and what could still change.
鈥楤igger gaps鈥 possible
Teams are guarding their development data, but what has become public suggests the slowest cars could be way off the pace.
Tire manufacturer Pirelli has confirmed to The AP that estimated lap times it has received from teams vary by as much as four seconds, a relative eternity in F1. Tombazis acknowledges new engine manufacturers may need extra development time to catch up on 鈥15 years of know-how鈥 from the likes of Mercedes.
F1 has a rule which could in theory rule cars out if their qualifying times aren’t within 107% of the fastest car. So could cars be deemed too slow to race?
鈥淚 think 107% is pretty unlikely, in my view,鈥 Tombazis said. 鈥淣ext year we have a wider level of uncertainty in performances, it鈥檚 absolutely true. . We have new regulations. Two of those things combined can mean that there could be bigger gaps in some places.鈥
The difference to 2025 could be stark. Despite McLaren鈥檚 dominance so far this season, six different teams have finished on the podium and less than a second has separated the entire field in some qualifying sessions.
Solving a 鈥榮care story鈥
F1’s strict testing rules mean these cars aren’t on track, they’re only in simulations made by the teams. Sometimes that can throw up alarming results, Tombazis said.
鈥淲hen there鈥檚 a scare story of 鈥極K, I drove the car and it did XYZ,鈥 in 99% of the cases (of) that XYZ that maybe has worried the driver or a team, we then sit down and resolve,鈥 he said.
One key area where rules could still adapt is how much work the drivers have to do. The new rules’ emphasis on electric power means judging when and how to deploy that power could be a key skill. It’s not yet clear how much of that will be automated.
Tombazis said the 鈥渆xtra work鈥 of managing a car is already a key skill and forms a big part of the team radio chat that is so popular with fans, but “what we don鈥檛 want to do is create a situation where it goes to the other extreme, where the driving becomes like a chess game where it鈥檚 just a matter of energy management and energy deployment.鈥
Avoiding 鈥榚ternal misery鈥
The new rules keep the turbo hybrid engine design first introduced in 2014, but with more emphasis on electrical power. Many in F1 expect Mercedes, whose engines have powered teams to nine constructors’ title since 2014, will be the manufacturer to beat.
Struggling manufacturers can get exemptions allowing them to spend above the cost cap to develop upgrades for engines which are deemed too uncompetitive or unreliable. The FIA will check every six races to see who is eligible for the boost.
The cost cap 鈥渋s essential for the financial sustainability of the sport, so I would obviously defend that to death,鈥 Tombazis said.
鈥淏ut on the other hand, it creates a problem that if you are behind in performance in a significant manner and you cannot outspend to recover the performance, you may be condemned to eternal misery by being eternally behind.鈥
It won’t be an instant fix. Tombazis emphasized. It just gives the manufacturer a chance to research a solution.
鈥淲e鈥檙e not adding any artificial performance to any car or artificial ballast on any car or anything like that,” he said. “This is absolutely not something that will ever happen in Formula 1.鈥
Racing in the rain
Full wet tires might be the least useful item in the whole F1 paddock. When it’s wet enough to use them, the tails of spray coming from the cars usually mean visibility is too poor to race.
That’s partly because of the aerodynamic floors on the current cars. So the next generation could potentially mean more wet racing.
鈥淚 would be lying if I said that we had complete confidence about how the cars will perform in the rain in terms of spray and visibility,鈥 Tombazis said, adding the FIA wants to stop a repeat of the , when no green-flag racing was possible.
鈥淲hen spectators pay a lot of money to spend the whole weekend sitting in attendance to watch a race and then eventually they have to go home (after very limited racing), that is absolutely terrible,” he said. “There鈥檚 a number of projects which are being evaluated in order to minimize the chance of that ever happening again and I think there are some promising trends.鈥
